1. The healthcare professional has collected the following information on a patient: palpated blood pressure"?180 mm Hg; auscultated blood pressure"?170/100 mm Hg; apical pulse"?60 beats per minute; radial pulse"?70 beats per minute. What is the patient's pulse pressure?
- A. 10
- B. 70
- C. 80
- D. 100
Correct answer: B
Rationale: Pulse pressure is the numerical difference between the systolic and diastolic blood pressure readings. In this case, the systolic blood pressure is 170 mm Hg, and the diastolic blood pressure is 100 mm Hg. Therefore, the pulse pressure is calculated as 170 - 100 = 70 mm Hg. Pulse pressure reflects the stroke volume, the amount of blood ejected from the heart with each beat. Choices A, C, and D are incorrect because they do not accurately represent the difference between the systolic and diastolic blood pressure readings provided.
2. Which of the following is an example of an environmental hazard that may put the healthcare professional at risk of injury?
- A. Loud noise from the hospital maintenance system
- B. Airborne powder containing latex
- C. Chemicals containing ethylene oxide
- D. All of the above
Correct answer: D
Rationale: Healthcare professionals, including nurses, are exposed to various environmental hazards that may negatively impact their physical or mental health. Hazards come in several forms, such as loud noise from hospital systems, which can damage hearing; airborne latex powder, leading to allergic reactions; and chemicals like ethylene oxide, a sterilizing agent that can cause cancer. Therefore, all the options listed pose risks to healthcare professionals, making 'All of the above' the correct answer. Choice A, loud noise, is a hazard that can affect hearing health. Choice B, airborne latex powder, can trigger allergic responses. Choice C, chemicals containing ethylene oxide, are hazardous and can lead to serious health issues. Each option represents a distinct environmental risk that healthcare professionals should be aware of and take precautions against.
3. What is the purpose of MSDS sheets?
- A. Contain the ordering information for each piece of equipment in the office.
- B. Are required by OSHA to be accessible to all employees of the office.
- C. Can be used to treat patients who have been injured in equipment accidents.
- D. None of the above.
Correct answer: B
Rationale: MSDS sheets, also known as Materials Safety Data Sheets, are essential documents that provide detailed information about chemicals used in the workplace. They are required by OSHA to be easily accessible to all employees to ensure they have the necessary information to handle chemicals safely. MSDS sheets do not contain ordering information for equipment in the office (Choice A) or serve as a treatment guide for injured patients (Choice C). Therefore, the correct answer is that MSDS sheets are required by OSHA to be accessible to all employees of the office.
4. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?
- A. MAP is the pressure of the arterial pulse.
- B. MAP reflects the stroke volume of the heart.
- C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
- D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.
Correct answer: C
Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.
5. When a patient refuses to believe a terminal diagnosis, they are exhibiting:
- A. Regression
- B. Mourning
- C. Denial
- D. Rationalization
Correct answer: C
Rationale: Denial is a defense mechanism where a patient rejects a reality that is too painful or difficult to accept. In the context of a terminal diagnosis, the patient may refuse to believe it in order to avoid facing the harsh truth. Regression (choice A) involves reverting to earlier, more childlike behaviors and is not applicable in this scenario. Mourning (choice B) is the process of grieving a loss, which typically occurs after acceptance of the diagnosis. Rationalization (choice D) is creating logical explanations to justify unacceptable behaviors, which is not the case when a patient denies a terminal diagnosis.
